PENClL-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 418,376, dated December31, 1889.

Application filed May 13, 1889. Serial No. 310,551. (No model.)

To aZZ whom it may concern:

Be it known that we, JAMES T. MORGAN and I-IUBERT \V. MORGAN, both of\Vinsted, in the county of Litchfield and State of Connecticut, haveinvented a new and Improved Pencil-Sharpener, of which the following isa specification, reference being had to the annexed drawings, forming apart thereof, in which- Figure 1 is a front elevation, partly insection, of our improved pencil-sharpener. Fig. 2 is a side elevation.Fig. 3 is a transverse section taken on line 00 0c in Fig. 2, and Fig.4c is a side elevation of a modified form.

Similar letters of. reference indicate corresponding parts in all theviews.

The object of our invention is to provide an instrument for sharpeninglead-pencils quickly and perfectly without danger of breaking the point;also to furnish a convenient eraser to be used with the pencilsharpener,forming together an attachment adapted to be carried with the pencil.and changed from one pencil to another as the pencil is used up.

Our invention consists in a pencil-sharpener provided with a conicalcutting end having a stop for preventing the lead from projectingthrough the end of the sharpener.

It also consists in the combination, with the sharpener, of aspring-clasp for holding and guiding the pencil.

The invention further consists in the combination, with the sharpener,of an eraser which also acts as a protector to the point of thesharpener.

The sharpener A is formed of a hollow truncated steel cone having aportion of one side removed, leaving in the side of the cone thetapering slot a, and at the' same time forming the cuttingedge b. Thesmaller end of the conical steel cone is closed by a. cap 0,

which prevents the lead from projecting beyond the end of the sharpener.

The sharpener may be used independently of the other attachment; but weprefer to connect with it permanently a sleeve 13 of spring material,furnished with a slot cl in one side thereof for receiving and guidingthe pencil C; and to prevent injury to the pockets by the pointed end ofthe sharpener, and,further, to admit of carrying an eraser with thepencil, we attach to or form upon the sleeve B a tubular extension D,having in one side thereof an opening 6 for the escape of the chips, andin the end of the said tubular extension we insert a rubber eraser-tipf.

The pencil is sharpened by inserting it in the sleeve B and turning it,so as to cause it to revolve against the cntting-edge 1), therebyremoving the wood of the exterior of the pencil, reducing it to aconical form and exposing the lead at the end of the wood until the leadstrikes the cap 0, which limits the amount removed from the pencil.

Our improved sharpener gives a conical point to the lead, and the wasteof the pencil by the breaking of the lead or the forming of long pointswhich are easily broken is avoided.

In lieu of forming the cutting-edge straight, as shown in Fig. 1, we maygive it a spiral form, as shown in Fig. 4, with the advantage of adrawing out.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination, with the conicalpencilsharpener A, of the cap 0, attached to or formed upon the smallerend and closing it, substantially as specified.

2. The conical pencilsharpener A, provided with the cuttingedge b, thecap 0, closing the apex of the cone, and the slotted spring-sleeve B,attached to or formed integrally with the sharpener, snbstantiallyasspecified.
